Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Pregabalin | Pregabalin 150, 300, 450 or 600 mg/day orally twice daily (BID); individual titration based on number of seizures experienced once Level 1 (150 mg/day) was maintained for at least 7 days, and dose reductions based on intolerable adverse events. Escalation to next dose level allowed only after completing previous dose level for at least 1 week. | 78 | 329 | OG000 |
| Group 2 | Lamotrigine | Lamotrigine 100, 200, 400, or 500 mg/day orally BID; individual titration based on number of seizures experienced once Level 1 (100 mg/day) was reached and maintained for 7 days, and dose reductions based on intolerable adverse events. Escalation to next dose level allowed only after completing previous dose level for at least 1 week. | 58 | 300 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- Exit Due to Any Reason After 4-week Dose Escalation Phase
- Description
Number of participants who exited the study due to any reason after the 4-week dose escalation phase. Time in days, from first day of study treatment to day of exit after Day 28 of the study due to any reason (ie, last day on study medication) was inestimable. Participants who did not exit or did not reach this phase were right censored as of the last day on study medication.
- Time frame
- Week 4 up to Week 56
- Population
FAS. N = number of participants who entered maintenance phase of study and had seizure efficacy data. Time to exit for any reason after the 4-week dose escalation phase was inestimable as the survival estimate at the end of the maintenance phase was below 0.500.
